Statistical Analysis: Demographic and baseline characteristics will be analyzed by descriptive methods. We will analyze all outcome variables on intention to treat basis. The primary efficacy analysis will compare the mean peak lactate level at day 1 post-operatively between the RIPC group and the control group using student-t test. The purpose of the pilot study is to assess the safety and feasibility of conducting the study and as such the data (except the peak lactate level at day 1) will be analyzed with descriptive methods and not used for statistical inferential purposes. Analysis will be done only for the purposes of sample size calculation for the future larger RCT and to establish trends. All statistical tests will be two-sided with 0.05 level of significance. Data will be analyzed with Stata (version 10.0, Statacorp, Texas).
